Resetting of MCB
Sometimes MCB trips momentarily without any equipment failure. Drivers should try to reset MCB once. While resetting ABB make MCB, resetting screw below the respective circuit breaker turns to horizontal position from initial vertical position. This screw should be turned to vertical position first and then, MCB should be reset by lifting it’s handle. For resetting MG make MCB, handle should be pulled first downward towards offside and then in upward direction towards on to reset the MCB, otherwise the MCB will not hold. If it is needed to trip any MCB, trip it with proper procedure i.e. by rotating screw or by pressing tripper knob provided on MCB. Don’t trip any MCB directly and in VCB closed condition
